@kevin Wouldn't it also need to check to see if anyone the user is following had boosted it as well?
Another edge case to consider: what if it was posted before you started following someone but boosted afterwards? Still filter or let it through?
Do you also want to suppress boosts from old content, like if it is from a week ago? A year ago?
@kevin Also what about the reverse where the user posted something, you unfollow, then someone boosts it into your TL again. Seems like you definitely want to filter in that case.
Not that I have the time or skills to implement such a thing, I just have a true passionate for user requirements 😛
